2. General

The Eaton Arc Flash Relay 101 (EAFR-101) is a sophisticated micro-processor based arc flash protection relay including complete self-supervision functionality. It is designed to minimize the damage caused by an arcing fault (arc flash) by sensing light from the point sensor and tripping the circuit breaker sourcing the fault current. The EAFR-101 complete system self-supervision function provides the highest level of dependability by continuously monitoring all internal sys-tem functions along with external connections.

The EAFR-101 is designed according to the latest protection relay standards and is therefore suitable for installations in rough environments, such as utility, traditional or renewable power plants, off shore, marine, oil and gas, mining, steel, or any other heavy industry applications. It is also well suited for commercial and institutional electrical systems. The EAFR-101 is suitable for either medium voltage or low voltage switchgear and motor control center applications in both new and retrofit installations.

2.1 EAFR-101 FeaturesThe EAFR-101 is a multipurpose arc flash protection relay that can receive light from four different channels of light point sensors and can be applied for variety of applications. The EAFR-101 can be used as a stand-alone relay or as part of a more complex arc protection system through the binary bus. The EAFR-101 comes in 2 mounting styles. EAFR-101 is a vertical panel or door mounted package and the EAFR-101D is a horizontal DIN rail package.

Main features of EAFR-101:

●● (110 to 220) Vac / (125-250) Vdc auxiliary power supply;

●● Four arc point sensor channels (S1, S2, S3, and S4);

●● Two binary inputs (BI1 and BI2) nominal voltage of 24 Vdc;

3. Operation and Configuration



3.1 LED Indicator FunctionsTThe EAFR-101 contains 11 indication LEDs. A user defin-able text pocket can be slid in under the label for identifying each LED function (except Power and Error LEDs). LEDs are located at the front plate of the relay for clear viewing without a need for opening doors.

During power up, the relay performs a LED test. All LEDs are turned on for two seconds and then off. Only the blue Power LED will remain ON. After powered up, the relay goes into protection mode in 50 ms even while the LED test is being performed. During normal operation only the blue power LED is ON.

The point sensor LEDs are off during the inactive condi-tion. If a point arc sensor is activated, the corresponding sensor channel LED will turn on if the activation is longer than 1.5 ms. The sensor LED activation function is latched (steady light). To clear the LED, the “Set” button should be pressed.

3.2 LED Operation Quick Guide

Table 1. LED Operation Quick Guide.

LED Off Steady On Blinking Action if Abnormal

POWER - Blue Auxiliary supply disconnected.

Auxiliary power connected. N/A Check the power source.

ERROR - Red System healthy. System failure. Configuration mismatch. Protection partly operational.

Verify system condition. See Sections 11: Troubleshooting Guide and 5: System Self-supervision.

T1, T2, T4 - Red Normal status. Trip relays T1, T2, T4 acti-vated.

N/A Check the reason for trip. Clear the fault and reset indications by pushing SET button.

T3 - Red Normal status. Trip relay T3 activated. N/A Check the reason for trip. Clear the fault and reset indications by pushing SET button.

S1 - Amber Normal status. Sensor channel 1 activated by light information

Sensor channel 1 has loose connection or the system set-up was not performed. Also activated by pressure information.

Check why the sensor activated, check the sensor wire connection, or perform the system set-up (see Section 3.3.1: Auto-Configuration (System Setup).

S2 - Amber Normal status. Sensor channel 2 activated by light information.

Sensor channel 2 has loose connection or system set-up not performed. Also acti-vated by pressure information.

Check why the sensor activated, or check the sensor wire connection, or perform system set-up (see Section 3.3.1: Auto-Configuration (System Setup).

S3 - Amber Normal status. Sensor channel 3 activated by light information.


Check why the sensor activated, or check the sensor wire connection, or perform system set-up (see Section 3.3.1: Auto-Configuration (System Setup).

S4 - Amber Normal status. Sensor channel 4 activated by light information


Check why the sensor activated, check the sen-sor wire connection, or perform system set-up (see Section 3.3.1: Auto-Configuration (System Setup).

S5 - Amber Normal status

BI1 - Amber Normal status. Binary input 1 activated. Binary input 1 has loose connection. Check the binary input wiring.

BI2 - Amber Normal status. Binary input 2 activated. Binary input 2 has loose connection. Check the binary input wiring.

BO1 - Amber Normal status. Binary Output activated. N/A N/A

In case of a loose sensor wire or configuration mismatch (new sensor attached without running auto-configuration system setup [see Section 3.3.1) situation, the correspond-ing LED for that point sensor will start flashing and the Error LED will activate.

The Binary I/O LEDs are indicating the I/O-line status. If any of the lines become active for more than 1.5 ms, the corre-sponding LED will turn on (latch).

In a trip situation, the corresponding trip LED will turn on. Trip outputs are controlled by the dipswitch settings (see Section 3.5).

All activation and trip indication LEDs are latched, even if the dipswitch setting is in the non-latched mode. They have to be cleared by pushing the “Set” button.

LED indications are stored in non-volatile EPROM memory for identifying the trip information in case the auxiliary power is lost. When re-powering the relay after power sup-ply loss, the actual LED status can be visualized from the front of the relay.

3.3 Push-button DescriptionThe EAFR-101 contains one single push-button (SET) that can be used for all operational functions of the relay. The push-button is used to initialize the auto-configuration of the system (see Section 3.3.1) and for resetting the indicators and latched output relays.

3.3.1 Auto Configuration (System Setup)When all sensors and binary lines have been connected, an auto-configuration procedure must be executed. The initial-ization sequence is performed by pressing the “Set” button for two seconds. The EAFR-101 sensor LEDs and BI1/BI2 LEDs start blinking. The relay scans these inputs to see if they are connected and when an input is detected, the cor-responding LEDs are illuminated to mark that a connection was found. The inputs without connection continue blinking during the remaining three seconds. After five seconds, all LEDs are turned off. During this system setup, the dip-switch setting are also stored in non-volatile memory.

All sensor inputs will remain operational even when they are not auto-configured. The auto-configuration is only used for self-supervision purposes.

otee:N To redo auto-configuration for a relay containing less connections (binary inputs/outputs or sensors) than in a previously memorized set-up, a dip-switch (any-one) must be moved back and forth prior to perform-ing auto-configuration. The timeout allowing a new configuration is one minute. Reconfiguration with more connections is allowed without moving a dip-switch.

3.4 ResetAll LED indications and latched trip relays are reset by pressing the “SET” button for one second. Otherwise, the latched trip relays will remain activated until auxiliary power is disconnected. All LED indications will remain active until reset is performed by the operator, even when auxiliary power supply is disconnected (see Section 3.6: Non-volatile Memory).

3.5 Dipswitch SettingsEAFR-101 functionality, such as tripping logic, is configured using dipswitch settings. Different trip configurations can be easily programmed by selecting the appropriate dip-switch positions. This gives users the flexibility to change settings dependent on the application. Tripping may be selected based on arc light only or arc light and current thresholds (or other tripping criteria such as under-voltage, or similar). Current threshold or other tripping criteria may be applied to binary input BI1 for blocking a trip caused by natural light sources. Also, the CBFP configuration may be enabled using the dipswitches. Dipswitches are located at the back of the relay for easy access (see Figure 4: EAFR-101 Dipswitch SW1 and Table 2: EAFR-101 Dipswitch Setting Selection for details of settings).

3.6 Non-volatile MemoryAll critical system data, including dipswitch settings and auto-configuration file described in Section 3.3.1, are stored in EPROM non-volatile memory to ensure correct operation and full self-supervision, even if auxiliary power is temporar-ily lost.

Also, all LED indications described in Section 3.1 are stored in non-volatile memory in order to provide quick recovery of the system status indication, even if auxiliary power is tem-porarily lost. This feature is especially important if auxiliary power is lost after tripping.

Non-volatile memory does not require a power supply to maintain information and will retain settings and indications permanently without power.

4. Arc Sensors

The EAFR-101 relay series provides the use of point arc light sensors to be utilized in different switchgear types, accord-ing to the specific application requirements. Arc light point sensors are typically installed in metal clad compartments, providing quick accurate location of the faulted area.

4.1 Arc Light Point Sensor EAFR-01The EAFR-01 is an arc light point sensor with a light sensi-tive photodiode element activated by receiving arc light. The EAFR-01 arc sensors should be mounted in the switch-gear cubicles in such a way that the light sensitive part can receive light from the protected area. Typically, one sen-sor per closed metal clad compartment is used. In open spaces, such as the busbar section, arc sensors should be mounted at a maximum of two meters (6.56 ft) apart.

The fixed light sensitivity of the EAFR-01-A sensor is 8000 Lux. The sensor does not require any user settings. The point sensor’s light detection radius is 180 degrees. Other point sensors are available with different Lux sensitivities, EAFR-01-B at 25,000 Lux and EAFR-01-C at 50,000 Lux.

Figure 7. EAFR-01 Arc Light Point Sensor.

4.1.1 EAFR-01 Installation and WiringThe EAFR-01 point sensor can be installed either on or through the compartment wall. An example of on the wall mounting is seen in Figure 8. The EAFR-01 is fixed against the wall using two screws. The same screw pat-tern is utilized in a through wall mounting arrangement. In this arrangement the unit is turned around and the point of the eye of the photodiode sensor protrudes through a small hole cut in the wall. The point of the sensor now faces the compartment to be protected. This allows for the body of the sensor and cabling to be located outside the compartment. For both types of installation, two screws are attached from the back side of the sensor. No external mounting plates are needed.

The cable to be used for wiring to the sensor should be a shielded, twisted pair cable. Table 5 lists several cables that can be used. Equivalent cable styles are acceptable to be used for the dielectric and temperature requirements of the application. Cable connectors are located beneath the covers that can be conveniently detached for fastening the sensor wires. The cover will be attached after installing the wires. Cable connectors are located at both ends of the sensor for series connecting a maximum of three sensors in one line (see Figure 9).

4.3.1 Arc Light Point Sensor EAFR-01 Connection1. Open the sensor side-covers, then detach the plug-

gable connectors from the sensor PCB, and prepare the twisted shielded pair cable connecting (see Figure 10).

Figure 10. EAFR-01 Sensor Connection.

2. Before connecting the cable to the connector, make sure that the connecting order is correct (+, signal, and shield). The appropriate pin information is shown on the blue bottom part of the sensor. Plug the wires into the connectors and fasten them by using a screw driver (see Figure 11).

Figure 11. Location of the PIN Information and Securing the Cable.

3. Connect the other end of the cable to a sensor channel on the EAFR-101 or EAFR-110P relay (see Figure 12).

5. System Self-supervision



9. A maximum amount of three arc sensors can be daisy-chained to the same sensor input on the EAFR-101 relay (see Figure 18).


The Auto Configuration is a part of the Self Supervision Function which ensures that all connections and sensors are fully functional and ready to operate at all times.

5. System Self-supervision

The EAFR-101 includes an extensive self-supervision fea-ture. Self-supervision includes both internal functions and external connections. The self-supervision module monitors power supply, hardware and software malfunctions, and binary input connection and sensor problems. Dipswitch settings are also supervised by comparing the actual value with stored non-volatile memory data (see Section 3.3.1: Auto Configuration [System Setup]).

In a healthy condition, the POWER LED is on and the System Failure (SF) relay is energized. If the self-supervi-sion function detects a faulty condition or the power supply fails, the self-supervision relay is released and the ERROR LED is illuminated.

If a sensor failure occurs, the relay will go into the ERROR mode. The ERROR LED will turn on, the SF relay will de-energize, and the corresponding faulty sensor channel LED will start blinking. In this situation, the relay is still in protec-tion mode, but with the faulty sensor channel blocked. If the error is resolved, the relay will automatically clear the SF-status. This means that the SF relay will energize and the ERROR LED will turn off. If one or more of the sensors are disconnected, the healthy sensors remain in use and the relay remains operational. The EAFR-101 will remain in Error mode until the disconnected sensors are repaired.

If a dipswitch setting is changed after the auto-configuration function (see Section 3.3.1: Auto Configuration) has been executed, the relay will go into SF alarm mode. The con-figured (stored) setting is however still valid and the relay is still operational.

6. Application Examples

The EAFR-101 may be applied to a variety of power switch-gear and control gear layouts and technologies. Some typi-cal applications are described in this section. Please consult your nearest Eaton representative for a solution to your particular application.

6.1 MV or LV Application with Current and Light ConditionThe EAFR-101 may be applied requiring both over-current and arc light conditions for trip. In this application, tripping is performed only if both conditions are fulfilled simultane-ously. Typically, the over-current condition is obtained from an EAFR-110 relay and the trip relay will be activated in 7 ms. The over-current condition may also be monitored by non-Eaton products (e.g.: generic feeder protection relay) and the total operation time is then dependent on device feeding the over-current signal to the EAFR-101.

The sensor channel S1 can be set to operate on arc light only, even if other channels operate on both conditions of arc light and over-current.

Figure 19 shows an example of a system applying both over-current and arc light for tripping from the sensor chan-nels S2, S3, and S4 activations and arc light only from sen-sor channel S1 activation. The S1 channel is monitoring the transformer feeder bus duct above the current monitoring point. a maximum three arc light point sensors type EAFR-01 can be connected to each sensor channel.

The current monitoring signal is in this application coming from an external over-current relay.

6.2 Wind Power Application Example (Light Only Condition)The EAFR-101 may be applied using arc light only as the tripping criteria.

The example in Figure 20 shows a typical wind power scheme where a permanent magnet synchronous genera-tor (PMSG) is applied with a converter cabinet and LV/MV transformer.

The EAFR-101 is equipped with four point sensor chan-nels and each channel may have up to three sensors (type EAFR01) connected in series allowing for up to 12 point sen-

sors. In this application, three sensor channels with three sensors in each channel are utilized. In the event of arc light in any of the compartments containing a sensor, the EAFR-101 relay will execute a trip to all three circuit breakers in 7 ms thus clearing the arc fault in total time of 7 ms + CB opening time. Additionally, an electronic lock-out relay (T3) is utilized to provide the lock-out function ensuring the fault is recognized and corrected prior to putting the generator back into service (safety loop).

7. Connections


6.3 Circuit Breaker Failure Protection (CBFP)The EAFR-101 includes a selective circuit breaker failure function which can be enabled by dipswitch setting (see Section 3.5: Dipswitch Settings). When enabled, the break-er failure function activates when the tripped breaker fails to operate. The breaker failure function is activated if the EAFR-101 detects the presence of light after a set operating time. When EAFR-101 is set to operate on light and current, both parameters must persist to activate CBFP. Breaker fail-ure can be set to operate either on 100 ms or 150 ms delay (Section 3.5: Dipswitch Settings).

7. Connections

7.1 Outputs

7.1.1 Trip Relays T1 and T2The EAFR-101 relay has integrated trip relays T1 and T2 for tripping of the circuit breakers. The T1 and T2 relays are nor-mally open type (NO).

7.1.2 Trip Relays T3 and T4The T3 relay output may act either as an electronic lock-out relay or as a trip relay. This option must be specified when ordering. When the T3 is factory configured as electronic lock-out relay, it is normally open type (NO) and will hold its position until manual reset command or until auxiliary power supply is lost. When re-applying the auxiliary power supply, the electronic lock-out relay will return to the contact condi-tion prior to loosing the auxiliary power. This NC relay out-put can be used for tripping contactor controlled devices.

Alternately, the T3 relay can be ordered as normally closed (NC) type relay EAFR-101B, EAFR-101DB.

The T3 relay follows the operation of T1 and activates when-ever T1 is activated.

Trip relay T4 is a common trip relay that operates anytime the T1 or T2 relay operates and can be used either for trip-ping one more disconnecting device or for trip alarm to local or remote monitoring and alarming system.

7.1.3 Binary Output BO1One binary output is available (+24 Vdc). The binary output function can be configured using dipswitches (see Section 3.5: Dipswitch Settings).

otee:N The binary output is polarity sensitive (see Section 8: Wiring Diagram).

otee:N When the EAFR-101 receives an over-current signal from a non-Eaton device, the actual operation time depends on the operation time of the external device and so total operational time cannot be specified or guaranteed.

BI2 can be used for receiving a trip signal or arc light signal. The BI2 can be used for receiving a trip signal or arc light signal. The function of the BI2 is configured using dip-switches (see Section 3.5: Dipswitch Settings).

The inputs are activated by connecting a dc signal exceed-ing the specified nominal threshold level of the correspond-ing input. The nominal threshold level is 24 Vdc. The actual activation of the binary input occurs at 80% of the specified nominal threshold value (i.e.: 19 Vdc).

7.3 Auxiliary VoltageThe auxiliary power supply voltage is (110-220) Vac / (125-250) Vdc. After powering up the relay, protection is active and operational within 50 ms.

7.1.4 System Failure Relay SFThe system failure (SF) relay is a form C type (NO/NC) and is energized in the healthy condition. Whenever the EAFR-101 detects a system error or disconnection of the auxiliary power supply, the contact changes its state. The state of the SF relay remains the same until the relay returns to a healthy condition and the SF relay is again energized.

7.2 Inputs

7.2.1 Arc Sensor Channels S1, S2, and S3EAFR-101 has four arc point sensor channels. Maximum three arc point sensors (type EAFR-01) may be connected to each channel.

For details on sensors, refer to Section 4: Arc Sensors.

7.2.2 Binary Inputs BI1 and BI2The EAFR-101 contains two binary inputs. The BI1 is always reserved for second trip criteria signal. In the most typical application, the EAFR-101 is receiving over-current information from the Eaton EAFR-110 device. Over-current information may come also from a non-Eaton device (e.g.: an upstream protection relay). Alternately, any other signal (such as under-voltage, or similar) can be used as second trip criteria along with light information.

Figure 24. EAFR-101 Cut Out for Panel Mounting (mm [in.]).

10. Testing

It is recommended that the EAFR-101 relay be tested prior to substation energizing. Testing is carried out by simulating arc light to each sensor and verifying the tripping and LED indication. For arc light simulation, a superior camera flash type is used: Canon Speedlite® 430EX or equivalent. For testing of non-latched signals and the CBFP function, use a Mini Maglite® 2 Cell AAA or equivalent type of flashlight. Check that the camera flash or flashlight has fully charged battery(ies) when testing.

10.1 Carrying Out Testing in the Light Only Mode1. Check that the dipswitch setting positions are in accor-

dance to your application.

2. Activate the camera flash within 20 cm (7.87 in.) of the EAFR-01 to be used.

3. Verify that the corresponding sensor channel indication LED status is changed to ON.

4. Verify the relay output(s) activation(s) by checking the circuit breaker status or by monitoring trip contact sta-tus. The circuit breaker should open or contacts oper-ate.

otee:N A best practice is to operate the circuit breaker dur-ing testing.

5. Verify that the corresponding relay output(s) LED(s) indi-cation status is changed to ON.

6. If the binary output (BO1) signal is utilized, verify the BO1 signal activation by the status change of the rele-vant input where the binary output signal is connected, or by measuring the signal output voltage.

otee:N The BO1 signal is a non-latched type.

7. If a binary output signal is utilized, verify that the BO1 LED is illuminated.

8. Press the SET push-button to reset all indications and latches.

9. If a binary input BI2 is utilized as master trip to activate the corresponding binary input, verify that the trip has occurred by repeating Steps 4 and 5.


11. Repeat the testing procedure for all sensors.

2. Activate the camera flash within 20 cm (7.87 in.) of the EAFR-01 to be used.

3. Verify that the sensor channel indication LED status is changed to ON.

4. Verify that the binary input BI1 indication LED status is changed to ON.

5. Verify the relay output(s) activation(s) by checking the circuit breaker status or by monitoring trip contact sta-tus.

otee:N A best practice is to operate circuit breaker at test-ing. The circuit breaker should open or contacts operate.

6. Verify that the corresponding relay output(s) LED(s) indi-cation status is changed to ON.

7. If the binary output (BO1) signal is utilized, verify the BO1 signal activation by the status change of the rele-vant input where the binary output signal is connected, or by measuring the signal output voltage.

8. If the binary output signal is utilized, verify that BO1 LED is illuminated.

otee:N The BO1 signal is a non-latched type.

9. If another binary input BI2 is in use, verify correct oper-ation by activating the input.

10. Activate the camera flash within 20 cm (7.87 in.) of the EAFR-01 to be used and do not activate the binary input BI1 used for over-current condition.

11. Verify that no trip has occurred and only the sensor acti-vation indication LED is ON.

12. Verify that the BOUT signal is activated (if in use and configured to send light information).


14. If the binary input BI2 is utilized for master trip to acti-vate the BI2, verify that a trip has occurred by repeating Steps 4 and 5.


16. Repeat the testing procedure for all sensors.

10.3 Testing the CBFP FunctionThe circuit breaker failure function is tested by leaving light signal and second trip criteria signal (e.g. over-current), if applicable, active for above the set CBFP time of either 100 or 150 ms. The trip relay T2 and binary output BO1 should be active after the set time delay.

10.4 Testing the Arc Flash Protection Unit Operation TimeThe EAFR-101 operation time test is not required at com-missioning as it is performed by Eaton as a type test and routine production test. Refer to the routine test reports sent with EAFR-101 relay and consult your nearest Eaton representative for type test reports.

However, if it is deemed necessary, a site timing test may be conducted using the following instructions.

1. Use a calibrated relay test set.

2. Connect an output from the relay test set to the cam-era flash (Metz® 20B1 or equivalent input) for initializing the flash and configure a relay test set timer to be started simultaneously with flash.

3. Connect the EAFR-101 trip output T1, T2, T3, or T4 to the relay test set input and configure the input to stop the timer.

4. Place camera flash to a maximum 20 cm (8 in.) dis-tance of the EAFR-01 or EAFR fiber sensor.

5. Initiate the flash and timer using the relay test set out-put.

6. Read the measured time between simulated arc and trip contact operation.

7. Subtract the digital input delay of the relay test set from the final measured time if applicable. For specific test instructions consult the manufacturer of the relay test set.
